Experience

OCR Text Reading

I enhanced the existing UiPath OCR engines by applying string parsing, validation, and manipulation, significantly improving text reading accuracy. The project included extensive testing and engine comparison analysis.

UiPath Custom Activities

I handled the creation of UiPath custom activities (using Visual Studio and C#) for Word document processing, as UiPath has a small number of default activities available for this type of document processing.

Document Understanding

I created a document understanding model using UiPath AI Center to read and process scanned invoice documents. The model would classify the document, extract information, and send it downstream for further processing.
